not sure whether the observed behavior (with gretl 2023c) with the

open denmark

gnuplot --inbuf=s --output=display { set title 'My Title';} # fails
</hansl>
Two questions:
- The first gnuplot invocation works, but it also produces a displayed
plot. Is this intended even though the outbuf option is given? I would
have thought that it only writes the output to the string s, not also
displaying something.
On Linux the plot is not displayed in this case; I'll have to try on Windows.
- The second gnuplot line yields a parser error. Is the inbuf
option
incompatible with further added gnuplot commands?
So it would seem. I'll look into it, but it seems reasonable that if
you've already created a plot buffer there would be no need to mess
with it further. In the example, "My Title" is shown via the second
gnuplot command (if the "{ set ... }" addition is dropped) since it
was specified when the buffer was created.
